A330 Go-Arounds
We routinely practice Go-Arounds from 50 feet above the runway both with A/P on or off. With A/P on it's a walk in the park as the rotation is managed by the auto-pilot and very little height is lost althought the airplane may touch down briefly.
With the A/P off its not much different except you manually rotate the aircraft to the G/A attitude. Once you have 100 AGL you can renengage the A/P.
I should say that this maneuver is usually accompanied by a loss in thrust of one engine just to make it as difficult as possible but even on one engine at heavy weight and high temperature the aircraft can go around from very low altitude safely.

PS I am not saying this is what this crew should or could have done since we really just speculating here.
